vBulletin X-Cart Integration

Due to popular request, we have written an x-cart and vbulletin integration guideline for shared user profiles.  The x-cart/vbulletin integration works by transferring all user aspects (registration/update/login/lostpass) to x-cart, and then using x-cart to keep the vbulletin database up-to-date. It provides the necessary class file for user functions and instructions for installation of the class file, a script to migrate users from x-cart to vbulletin, and a guideline for integration into your vbulletin templates.  You can see the integration at work on the forums of WebsiteCM.
